0rigina1 application filed :May 28, 1925, Serial No. 33,352 Divided andthis application filed January 18, 1926. Serial No. 81,959. g n t i 2 Myinvention relates to lasts, and partic-' ularly to collapsing lasts, andis a division of my application'filed May 28, 1925,

Serial No. 33,352.

It is the object of my invention to provide a collapsing last with theparts pivotally mounted one on the other moving about a given center ofmovementwithsuch parts connected together by a solid link, the ends ofwhich are adapted to yield or open to permit the movement of the lastparts from one position to the other and to hold them in a givenposition when so moved. 7

It is my object to providea flat spring plate having such yielding endsas to permit of the movement of the last parts and to yieldingly resistsuch movement.

It is a further object to provide a straight plate link the ends ofwhich permit of this yielding feature thus eliminating aspring.

It is a further object to mount this plate with the spring ends onanchpr pins so aiw ranged that a l1ne drawn between the centers thereofwill pass over the center of,

movement of the last partswhen the parts are moved and the ends of thelink are flexed.

Referring to the drawings: Fig. 1 shows a last embodying one form of myinvention, with the last partially in section; and

Figure 2 illustrates a modified form. Referring to the drawings indetail, 1 is a toe part having a slot 2 for accommodating the link. Therear face of the toe part is de iated 3. t Locaed transversely of therear face 3 of the last part 1 and across the opening of the slot 2 is asemi'cylindrical groove 4 for receiving the projecting circular shoulderor knuckle 5 carried by the heel part 6, on the forward face of thisheel part which is vertical at Tto form a shoulder abutting against theshoulder 8 of the toe part, but this face is cut away at 9 to permit ofthe collapsing of the last parts. The

The bridge member end of the link 21 1S convex toforms resisting spring bridge member; lVhen the parts pass over deadcenter the 'line'or distancebetween the centers of the, anchor pinsbeing lengthened by reason of the movement of the parts on theeccentrically curved faces 4 and 5 the end members 21 are flexed, whichflexing causes the slots 19 to spring open; This yielding ofthe ends ofthe link permits of the movement of the parts from one position to theReferring to Figure 2, there will be ob servedanother form of link whichconsists of aplate link having a solid central portion 22 with enlargedheads 23 which are provided with a centrally located .slit 2% whichextends inwardly to the base of aX-i-"haped slot 25 in which is locatedthe anchor pin. hen the parts moveover dead center this slit 24 opens byreason of the pressure of the pins12 and 13 against each side of theends 23, as will be apparent from an inyieldingly. I

It will be understood that I desire to con prehend within my inventionsuch niodiii-, cations and changes as may be necessary to adapt it tovarying conditions and uses.

Havingthus fully described my invention, what I claim as new and desireto se cure by Letters Patent, is:

and either side" 7 slot 18. The slot 18 is widened at the center.

1. In a last having a toe part and a heel part adapted to rock upononeanother about a given point, a linkconnecting said parts said linkhaving spring ends adapted to flex to permit the parts to move from oneposition to the other, the center of said link loeing inflexible, saidlink consisting end thereof to permit of the flexing of the ends of thelink, said slots having associof a plate, said plate having slots ateach ated therewith longitudinally arranged slits for permittingportions of the link to spread.

2. In a last, a heel part and a toe part adapted to rock about oneanother about a given center of movement, a plate link of substantiallyrectangular form, anchor pins for the ends of said link, the ends ofsaid link being arranged to yield ant ilex when the parts are moved fromone position to the other, said flexing being permitted by slots cut inthe ends of said link, and slits in said link associated with said slotsto permit portions of the link to spread.

3. In a last, a toe part and a heel part adapted to rock one on theother, a plate link connecting said last parts, an anchor pin in each ofsaid last parts supporting said link, transversely arranged slots in theends oi said link, said link having slits extending inwardly from saidslots in said link. 20

In testimony whereof I a'liix my signature.
